### Instruction:
Give an example of how the law of conservation of energy is applied in a real-life situation.

### Response:
assistant
The law of conservation of energy is applied in a real-life situation when a car engine converts fuel into kinetic energy. In this process, the energy of the fuel is converted into mechanical energy, which is then used to move the vehicle along the road. This conversion of energy follows the law of conservation of energy, where the total amount of energy (both potential and kinetic) before the conversion remains the same afterwards.
